The following is in response to your telephone request for
information on elevations, ownership, etc. on properties adjacent
to the Avero House.

1. The invert elevation in the catch basin on Castillo
Drive immediately to the south of the driveway to
Michele's restaurant is + 1. 5' MSL.

Z. This catch basin was state constructed and would
require DOT permission to tap.

3. Property ownership is designated on the attached
sketch map.

4. Archaeological clearance would be required for
that portion of the proposed drain that traverses
State property as well as an "as built" location
drawing. Clearance would depend on the magnitude
of the job. A small ditch would simply require a
competent observer/recorder.
